A testicular ultrasound is a safe, painless procedure that uses sound waves to create images projected onto a computer monitor of a man's scrotum and testicles and nearby structures. During the procedure, an ultrasound technician applies a clear gel to the scrotal sac, then moves a small, hand-held device called a transducer gently over the gelled area. High-frequency sound waves are transmitted from the transducer through the gel to the structures in the scrotal area and then bounce back to a computer that uses those sound waves to create an image on the screen.

A testicular ultrasound (or scrotal ultrasound) may be used to help diagnose the cause of several different symptoms including:
  • enlargement of the testicles
  • lumps or masses in one or both testicles
  • testicular pain
  • infertility
  • undescended testicles
  • impact of trauma to the area
In most cases, a radiologist will interpret the results of a testicular ultrasound and confer with your primary care doctor to determine whether you need treatment, further testing, or follow-up care..
